windows下JMX串連Tomcat

OS：win7

jdk：1.6

Tomcat：7.0.26

1.Java的環境變數配置正確，網上很多，不再說了

2.修改Tomcat目錄下的bin\catalina.bat

在該檔案中尋找set JAVA_OPTS=%JAVA_OPTS%，下面有一行為：

rem ----- Execute The Requested Command ---------------------------------------

在這一行的下面加

set JAVA_OPTS=-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9008 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false

說明：9008為連接埠號碼，一會兒要用到。很多地方說tomcat需要許可權驗證，可是我這裡沒有用到，就可以串連成功，所以沒有測試密碼檔案，僅將Dcom.sun.management.jmxremote.authenticate的值設為false。

3.記得編輯完bin\catalina.bat後，一定要雙擊執行。直接雙擊就可以，不要在cmd中執行，我執行出錯（不知道為什麼）

4.雙擊bin\startup.bat，最好雙擊執行，我在cmd中執行，無法啟動Tomcat

5.在cmd中執行netstat -an，可查看到9008連接埠已經啟用，說明Tomcat的Jmx配置成功

6.在cmd中敲入：jconsole（這個exe令在C:\Program Files\Java\jdk1.6.0_23\bin，即安裝目錄的bin下），即可啟動jconsole的管理介面，在介面中輸入如下內容：

service:jmx:rmi:///jndi/rmi://localhost:9008/jmxrmi

或者

localhost:9008

即可進入管理介面，在管理介面的Tab頁MBeans中，可以看到所有的MBeans

此時，Jmx監控Tomcat配置成功！
